Hi @RandomNoob! I think you have a combination of heat stress and over-feeding. The leaves are curling upward, they're telling you that the canopy gets too hot, so raise your light up, increase your lamp-to-plant distance and make sure the canopy gets a cool continuous breeze / a decent airflow. Now they're also very dark green, and show some spots, the spots must have appeared because of a nutrients-lockout situation, and that situation was caused by too much nutrients / a high EC during the previous weeks. Do you have an EC-meter? If you give tap water, that water might be too hot for cannabis, adding OrganicGrowLiquid makes your solution too strong for your rootmass. At this stage, let the medium dry a bit then flush it with pure pH'd water (tap water that has been sitting for a few hours, or RO water), let it dry again (a small fan blowing on the container might help) and see how the plant reacts before adding nutrients again. If you do not have an EC-meter, go grab it asap to your local growshop, this will dramatically help you to understand what's your giving to your rootmass. Hope this will help, let us know how this goes, and happy growing! 👊
